How this entity was disambiguated
This entity first appeared as the object of triple T1151888 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Entity disambiguation (via context triple)
gpt-5-mini-2025-08-07
Target entity: Fourier optics Context triple: [Fraunhofer diffraction, mathematicallyDescribedBy, Fourier optics]
-
A.
Fresnel diffraction theory
Fresnel diffraction theory is a wave-optics framework that describes how light diffracts when source or observation distances are finite, using near-field approximations derived from the Huygens–Fresnel principle.
-
B.
Fraunhofer diffraction
Fraunhofer diffraction is the far-field diffraction pattern of waves, typically light, observed when both the source and observation screen are effectively at infinite distance or made so with lenses, producing characteristic interference patterns.
-
C.
Kirchhoff diffraction theory
Kirchhoff diffraction theory is a classical wave optics framework that models light propagation and diffraction by treating wavefronts as superpositions of secondary spherical waves emitted from an aperture.
-
D.
Principles of Optics
Principles of Optics is a seminal textbook that rigorously develops the theory of electromagnetic waves and optical phenomena, profoundly shaping modern physical optics.
-
E.
Applied Optics
Applied Optics is a peer-reviewed scientific journal focusing on research in optics, photonics, and related applied technologies.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Fourier optics Description of subject: Fourier optics is a branch of optics that uses Fourier transform methods to analyze and design optical systems, particularly the propagation and diffraction of light waves.
